The striker is back after his surprising omission at Old Trafford over the weekend. Campbell's appearance in the starting line-up will be his first since February 1. He has been troubled by problems with his ankle and then his toe until recently.
Philippe Senderos is rested to make way for Campbell. Wenger has also brought back Jose Antonio Reyes and Freddie Ljungberg. Francesc Fabregas will miss the game with a foot injury he picked up at Old Trafford. It is only expected to be a short-term problem.
"Campbell, Reyes, Ljungberg are back in squad," said Wenger. "[Against Manchester United], Ljungberg had as small knock from Juventus, Reyes was rested. He will be suspended against Villarreal next week so he can play in these games.
"Sol will start. It gives him a good opportunity to show that he's ready for us. I will rest Senderos, who finished tired against Manchester United."
Wenger admitted that he left out Campbell completely at Old Trafford so he could regain sharpness in training.
"That was the plan," said the Frenchman. "To get him to work hard rather than sit on the bench. We have eight games now on the trot - game after game - and I will have to rotate in every game now without destroying the balance of the team and the belief of the team. That's why I am happy that he's there. You could see on Sunday we were on top but the longer the game went on the more you could see we lost some strength."
Henry's omission at Old Trafford was also down to worries over fatigue.
"Thierry will be back on Wednesday," said Wenger. "You know the problem with Thierry. If you lose the game and don't play him then it's the wrong decision but what if he'd played, we'd lost and he'd picked up an injury? That would've been the wrong decision too. Whenever you lose a game you are wrong. I just felt he needed the breather."
